justin_smallwood Posted October 10, 2017 Author Report Share Posted October 10, 2017 Ok, for an update, I changed the vacuum to the side (as suggested) and I still have quite much fuel in my vacuum line, and having the same issues as before..is fuel in the vac line normal, or should I be looking for another issue?Sent from my LG-D722 using Tapatalk Quote Link to comment Share on other sites More sharing options...
registered user Posted October 12, 2017 Report Share Posted October 12, 2017 maybe its not the pumps fault. pull the lines off the carb and put em in a bottle and start the engine. your likely to have some premix in the suction line no matter what. its just that youll probly have more if the entrance is on the floor since the back of the reed cavity is where excess fuel oil seems to collect. maybe your pj is clogged. hard to say pumps have their place and time. like on machines that run upside down, on their side and near vertical conditions. snomos and watercraft come to mind. but really have no place on a atv imo. the only exception i could think of is the long 300' bikes where the tank is located in the nose and the fuel has to be pulled up to the carbs again i would get rid of that setup u have now. just me though. local classifieds, ebay or the f/s area should have what u need Quote Link to comment Share on other sites More sharing options...

But I paid quit a good amount for em, so not that easy to buy more..But I definitely see what u saying. Going to dyno the weekend. Hopefully get it figured out thenSent from my LG-D722 using Tapatalk Quote Link to comment Share on other sites More sharing options...
registered user Posted October 12, 2017 Report Share Posted October 12, 2017 another thing is the original float valve wasnt intended to flow the amount of methanol needed. billet bowls will likely help u. the stock bowls dont have shit for capacity. between the small bowls and the float valve, that could be your problem as well Quote Link to comment Share on other sites More sharing options...
registered user Posted October 12, 2017 Report Share Posted October 12, 2017 depending if your tuned alittle rich or alot rich, fuel consumption is some where around 2-2.5x of gas. so u can see why standard gas components dont work very good. bowls, float valves etc Quote Link to comment Share on other sites More sharing options...

hotrod9193 Posted October 12, 2017 Report Share Posted October 12, 2017 How is the diaphragm in your pump? Alcohol or methanol is bad about drying them up. Also try to replace all your lines if not already new any tiny cracks or holes in any of the components can cause all kinds of issues. I'm talking from experience I used to run them alot on alky and meth gas. Not on a banshee but still the same pumps. I'm thinking it's getting air from somewhere. Also I don't think it's been stated but what fuel valve are you running on your tank? What kind of tank and vent?Sent from my SM-G930R4 using Tapatalk Quote Link to comment Share on other sites More sharing options...
registered user Posted October 12, 2017 Report Share Posted October 12, 2017 its pretty well documented what the ball park consumption between gas and methanol is . and if u know how, u can also calculate it yourself based on airdensity , engine size and a few other factors Quote Link to comment Share on other sites More sharing options...

The fuel valve is a normal dual pingle with one closed off...and a stock tank with the cap gutted and drilled biggerSent from my LG-D722 using Tapatalk Quote Link to comment Share on other sites More sharing options...

I would replace it and give it a try. It seems to me like it's getting air "loosing pulse or vacume" from somewhere Sent from my SM-G930R4 using Tapatalk Quote Link to comment Share on other sites More sharing options...
justin_smallwood Posted October 12, 2017 Author Report Share Posted October 12, 2017 How does the diaphragm look so I'll know when I see it? Not familiar with those.. And yeah someone else said I may have an air leak somewhre. Getting a leak down test the weekend..Sent from my LG-D722 using Tapatalk Quote Link to comment Share on other sites More sharing options...
justin_smallwood Posted October 24, 2017 Author Report Share Posted October 24, 2017 Update...took the bike to a bud, and found hella leaks around the cylinders, as well as possible spark issues, my cool wires were taped to the coil, and I had plug caps that didn't ohm to 5k, change those to NGK caps, changed my 1/8 barb end to a 1/4 end (hose end) as well as a new coil, and cylinder gasket.., shortened up hoses for the vacuum and fuel, took to the dyno right after, and got the high 97 ponies. Guess not to bad. Finally ran it Sunday, and it ran flawless. Thanks for the advice I received and shout out to my budSent from my LG-D722 using Tapatalk Quote Link to comment Share on other sites More sharing options...
specialblend07 Posted October 24, 2017 Report Share Posted October 24, 2017 421 on meth should be doing better than that. But if you're happy den dats all dat matterz Quote Link to comment Share on other sites More sharing options...

But if you're happy den dats all dat matterzYeah I was told anything over 100 is ideal. I'm pretty sure if I had more sprockets to get mph I would have got better numbers. All I had access to was 16 41, low mph..Sent from my LG-D722 using Tapatalk Quote Link to comment Share on other sites More sharing options...
